2019 EO2

2019 EO2 belongs to the Apollo group of near-Earth asteroids, whose orbits cross the path of Earth; with a semi-major axis of 1.201 AU it takes 1.32 yr to circle the Sun.

Orbit and dynamics

Between its closest point (0.925 AU) and its farthest (1.476 AU), the heliocentric distance changes by 0.551 AU over every revolution.

One full revolution takes 1.32 yr (481 days), computed from the semi-major axis of 1.201 AU.

An eccentricity of 0.229 makes the orbit moderately elongated.

A steep inclination of 21.62° carries it well above and below the ecliptic plane.

By the vis-viva equation its orbital speed rises to 34.3 km/s at perihelion and falls to 21.5 km/s at aphelion.

Because q < 1 AU and Q > 1 AU, this orbit geometrically intersects the region of Earth's orbit.

Size and surface

No direct size measurement is available; from an absolute magnitude of H = 23.36 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.08 km.

Observation record and orbit quality

Astrometry from 88 individual observations underpins this orbit; the fit leaves an RMS residual of 0.3967 arcseconds.

Condition code U = 7 signals a poorly constrained orbit, so its future path should be treated as provisional.

About these computed values

Orbital periods, perihelion and aphelion speeds, and diameter estimates on this page are computed by SpaceAtlas from the JPL SBDB orbital elements. They are derived quantities, not values copied from the source catalogue.
